Description

The GeneChip™ Mouse Gene 2.0 ST Array and GeneChip WT PLUS Reagent Kit is a whole-transcript array that includes probes to measure both messenger (mRNA) and long intergenic non-coding RNA transcripts (lincRNA). This whole-transcript array design provides a complete expression profile of mRNA as well as the intermediary lincRNA transcripts that impact the mRNA expression profile.

Since the design of the GeneChip Mouse Gene 1.0 ST Array, there has been a substantial increase in the structural and functional understanding of the mouse genome. This increase in knowledge includes the identification of a large number of long intergenic lincRNA that have been identified by the research community. In order to provide the research community with a tool that can measure the differential expression of this exciting class of RNA transcripts, we designed the GeneChip Mouse Gene 2.0 ST Array. To supplement the lincRNA data contained in RefSeq, we used sequence and transcript data from lncRNA db (http://lncrnadb.com/).

Comprehensive Design of Gene Arrays
Research over the past 20 years has predominantly focused on protein-coding messenger RNA transcripts and their role in cellular processes, such as disease and development. Recently researchers have identified more that 2,000 transcripts (>200 bases) in the mouse genome with little or no protein coding potential. Only a small fraction of these non-coding RNAs has functional annotations to date. However, there is ample evidence that differential expression of lincRNAs plays an important role in the genesis and progression of disease and that aberrant expression of these molecules have also been linked to cancer. Recent advancements in transcriptome profiling provided evidence of the association of lincRNAs in diverse range of cellular functions:

• Regulation of mRNA transcription
• Regulation of mRNA post-transcriptional modifications
• Occlusion/recruitment of transcription factor binding
• Activation and transportation of transcription factors
• Interaction with accessory proteins
• Guide protein complexes to locations in the genome

Key Benefits of Gene Arrays
• Comprehensive coverage provides the best opportunity to discover interesting biology
   - >28,000 coding transcripts
   - >7,000 non-coding (include ˜2,000) long intergenic non-coding transcripts
• Measure alternative splicing events/transcript variants with probes designed to maximize exon coverage
• Reproducible: Intra-lot correlation coefficient = 0.99

GeneChip WT PLUS Reagent Kit
The WT PLUS Reagent Kit uses a reverse transcription priming method that primes the entire length of each RNA transcript, including both poly-A and non-poly-A mRNA to provide complete and unbiased coverage of the transcriptome. The kit efficiently generates amplified and biotinylated sense-stranded DNA targets, avoiding loss of specificity due to antisense strand interference.

The WT PLUS Reagent Kit includes the amplification module coupled with GeneChip WT Terminal Labeling and Controls Kit for preparing hybridization-ready targets from 50 ng to 500 ng of total RNA.


Features and benefits:
• A complete target prep kit with proven sensitivity and specificity resulting from an optimized design for WT arrays
• A low sample input requirement of 50 ng. The kit works with a variety of sample types, including fresh-frozen tissues, cell lines, and whole blood
• StreamLined workflow with no ribosomal RNA depletion requirement or a globin reduction step for blood samples
• Opportunities to bundle WT arrays with WT reagents, offering exceptional cost savings
• Convenient single source for ordering and support
